摘要

本篇報告三例因單側先天性或外傷性白內障摘除術後無晶體症及一例單側先天性白內障，接受角膜表層屈光矯治移植術(Epikeratophkia)的手術結果。其中三例是小孩，一例是成年人。這位成年病人因單側外傷性白內障術後，眼前葉結構無法適應隱形眼鏡或再度植入人工水晶體而接受手術。三例小孩在手術當中，一例同時進行白內障摘除術，一例同時去除膜性白內障。經過六個月以上的追踪檢查，四例的角膜片都移植成功。角膜弧度平均增加了9.86 diopters，要達正視平均尚須+0.69 diopters。由我們的臨床經驗可知角膜表層屈光矯治移植術可以有效地矯正無晶體症所造成的屈光異常。尤其適用於一歲以上小孩單側無晶體症，若無法適應眼鏡或隱形眼鏡以進行視力復健者，則可考慮接種這種「活的隱形眼鏡」。

This paper presents our experience in epikeratophakia of our first 4 consecutive cases. There were 1 adult and 3 children. They had unilateral congenital or traumatic cataract, and three of them had received cataract extraction. One patient had epikeratophakia combined with extracapsular cataract extraction and one coupled with a membranectomy.
With 6 to 10 months of follow-up, the results showed that all the grafts were successfully implanted. The average increase in corneal curvature was 9.86 diopters, and the average over-refraction needed to achieve emmetropia was +0.69 diopter spherical equivalent. All cases showed improvement in visual acuity.
This preliminary report shows that epikeratophakia is an effective procedure for pediatric aphakia or for some adult aphakia. This procedure facifitates visual rehabilitation especially in unilateral pediatric aphakic patients. Longer followup will be necessary to better define its role in the future.
